To all who-m it may concern Be it known that I, ROBERT P. STAA'rs, ofthe city and State of New York, have invented an Improvement in Claspsfor Elastic Bands, of which the following is a specification:

Clasps have been made in which the end of the elastic is received withina clip with teeth, and this is thrust into a at case, and held by aspring-latch but the entire strain of the elastic band is `taken uponthe sp1-in g-la-tch.

My invention consists in a clasp formed of a case with penetratinghooked teeth, turned inwardly toward each other at the ends, upon whichthe elastic band is pressed, and hooked by the action of removablespring-wedges. These wedges can he easily withdrawn for Y shortening theelastic band, and all the strain ofthe said band is taken upon the caseitself.

,ln the drawing, Figure l is a plan in larger size, showing the casewith the elastic attached at one end, and the other end of the casebroken open to show the teeth. Fig. 2 is a section of the same with theelastic attached at one end, and the other end of theelastic and springlwed ge separate.

The case a, of metal, has the teeth b at the ends turned inwardly, andpointing toward each other, so that the strain upon the elastic band ctends to force the teeth through the elastic band. Hence, to secure theelastic band to such case, it 'is only necessary vto pass the ends ofsuch elastic into the case, and insert the spring-wedges c, that pressthe elastic to the points of the teeth.

These spring-wedges are made of the folded strip of metal shown; and thethumb-piece or lip i' servespfor withdrawing the spring-Wedge when it isdesired to change the elastic.

I claim as my invention- The spring-wedges c, in combination with thecase a, having the teeth b at the ends bent inwardly, as and for thepurposes set forth.
